This Contact Lens interactive also includes:
How do contact lenses work? The simulation allows young scientists to explore focal length and lens type to see how and why contact lenses work. Pupils control the focal length for an eye and a lens, the type of lens, and the distance the person wants to see. A graphic of how light is traveling and the point at which it converges appears for each trial.
